Re: Containing Sprinkler Runoff.

I would also note a tale of two fires. My jurisdiction had a fire in a non-sprinklered industrial solvents distribution facility, Chemcentral. Operation was above clean, to neat, but pre-existing from a code perspective. Fire spread from non-"H" areas to engulf facility. We flowed 2 1/2 - 3 mill

In the range of considerations for a hazardous materials response infrastructure and environment are below life, and often above property in risk consideration. While release may be harder to quantify than a fixed property it is easy for damage down river to become logarithmic. See Basel fire, a

RE: Containing Sprinkler Runoff.

Containment needs to be determined at the beginning of a project. Where and why is it required, how will it be dealt with, what happens to the excess flow after the required 20 minutes of containment has been exceeded? Typically these are not sprinkler contractor questions, these are questions

If the facility was not sprinklered it probably doesn't contain any or minimal quantities of materials that are hazardous to the environment and require containment or spill control. Craig L. Prahl, CET Fire Protection CH2MHILL Lockwood Greene 1500 International Drive Spartanburg, SC  2

RE: Lift Equipment for Sprinkler Installation

It was my understanding that you may NOT use "home-made" supports anymore, and the "qualified" person (scissor lift manufacturer) did not design nor certify them. You must buy the Factory pipe cradles, or put the pipe on the floor of the lift. Jeff Garrison Project Engineer C 586-871-3705 Detroit

RE: Lift Equipment for Sprinkler Installation

Yes, we designed and manufactured a "bull horn" style pipe rack capable of supporting the pipe above the safety rail. We have now outfitted all of our Owned equipment, and have bolt on style racks for rental equipment. And thanks again to Ben for pointing our effort to OSHA. Mark at Aero -

Remember this from a few months ago. I read the OSHA link and Genie product link. Was the end result you cannot support the pipe or materials from the rails and must use something like the Genie product? Just seeing if I took from this an accurate summary of the conversation and if anythin

Steve was a tad softer on this issue which is an old point of contention for me. The older editions of NFPA 20 simply said where the pressure exceeds the rating of the system, a relief valve shall be installed. So some (we'll many) folks well golly gee willickers, we can overs die that baby, r

The building code provides direction regarding when containment or spill control is required. The local AHJ's "fears" need to be based on the requirements of the code based on the hazard present not his feelings. An analysis of the code requirements needs to be performed and based on that, a

I have seen dikes built up under the doors with ramps on either side for access. You might also look into a fog or mist system to reduce the water volume. Matt Grisé PE*, LEED AP, NICET II Sales Engineer Alliance Fire Protection 130 w 9th Ave. North Kansas City, MO 64116 *Licensed in KS & M

A fine way to perform what is seems you need to do. Don't forget the safety relief downstream and you really need to study when setting these for flow. I believe the max is still 165. TD There's also a master pressure reducing valve assembly (contains 2 primary PRV's, a smaller PRV to account fo
